If your using 93 octane your safe on the 91 tune. If you go to the 93 tune make sure you data log and keep an eye on Knock during WOT. Under no circumstances should you run the 93 tune on 91 octane your knock will be thru the roof. I have my challenger on the 93 tune. I pulled 3deg of timing and ...

Guys, there is no requirement for a 180 thermostat for the 93 tune or any tune of that matter. The tunes diablo rights are set for the factory 200 deg thermostat. If you install one you will need to lower all fan temps 20 degrees lower than the current setting. The thermostat does help keep the ...

I've got a 2012 RT 6M. When it was 34 degrees out I did 5.10 with the 93 tune.
Yesterday it was 72 out.

Stock tune- 5.76
93 tune 2% rich fuel-5.40

I was experiencing light knk with 91 tune also around 1600-1900 rpm with light throttle before the update. It was about 1-2 higher with the 93 tune on avg.

I am a fan of the 85mm throttle body for our cars. I've had it on the car for about 12000 miles never have thrown a code. I gained roughly 2/10 on the 1/8 mile. My best time before the tune with my mods was 9.18 with .246 sec. reaction time (Before 85mm throttle body 9.36, .253 reaction time) in ...

I tried this update tonight and I'm pretty pleased with the results. I have a 2012 challenger rt 6 speed. My mods on the car is as follows: k&n cai, Arrington 85mm throttle body, 180 thermostat, flowmaster cat back and added a catch can last week. I still got some light knock with the 93 tune under ...

Are you suppose to be able to select auto or manual transmission for the 2012 Challenger RT? I seen in a previous post this was asked and not answered. I have never been asked to select a transmission type. I have also checked in the options menu as well as change vehicle type and still nothing.

Yeah it did.

Ok I figured it out. I had to add a lot of fuel to get it to not knk. I also put better fuel in the car. Here is what I had to adjust too:
WOT. Knk st. Knk lt
1000-3800. :13. 0. 0
4000-4800. :11.5. 0. 0
5000-7000. :9. 0. 0

It's looking like right around 2800 rpms

Ok I did. I am now up to 7.5 for all 3. Here's my results.
Knk retard st-3.5
Knk retard fuel-3.5
Knk retard LT-0
Misfires-0

I have adjusted fuel in the 91 tune but still misfiring. On the 93 tune I am getting no misfires.
I started increasing fuel under the wot setting a 2 percent. I'm now at:
1000-3800-4%
4000-5000-5%
5000-7000-5%

Knk retard-3.5
Knk retard-1
Misfires-0
Is it safe to increase to more fuel, or is there ...

I actually think it made it worse. It was worse than my first log with 93 but better than the second. Also it had 7 misfires.

Just spoke to mike on the phone about 20 minutes ago. Told me to try the 91 tune. I did and here's my results.
Knk retard-7
Knk retard lt-3.5
Misfire count-7

Citgo, I'm pretty limited on gas stations in my area.
